Embodiment 5

[0206] Such as Figure 5 As shown, the method for data transmission in Embodiment 5 of the present invention includes:

[0207] Step 500, the network side device determines whether the serving cell cannot meet the service data transmission requirements according to the BLER of the serving cell of the UE or the BLER of the UE in the serving cell;

[0208] Step 501. The network side device deactivates or configures the serving cell after determining that the serving cell cannot meet service data transmission requirements.

[0209] Such as Figure 6 As shown, the method for configuring the downlink BLER of perUE according to Embodiment 6 of the present invention includes:

[0210] Step 600, the eNB (base station) sets the BLER index of the downlink perUE to 10%.

[0211] Step 601, the eNB performs perUE-level BLER statistics on the UE according to its own scheduling situation, wherein when HARQ transmission is performed, the transmission block that fails to be transmitted (inc...

Abstract

The invention discloses a service data transmission method and apparatus for solving the problems of relatively low success rate of data transmission and poor user experience of a method for UE achieving transmission in an LTE-U carrier cell by means of carrier aggregation in the prior art. The method of the invention comprises that a transmitting device transmits service data through a first cell in an unlicensed spectrum; the transmitting device determines a second cell after determining that the first cell cannot meet the transmission requirement of the service data; and the transmitting device transmits the service data through the determined second cell. Since another cell is determined for transmitting the service data in the embodiment of the invention when the cell in the unlicensed spectrum cannot meet the transmission requirement of the service data, the success rate of data transmission is increased, and thus the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a service data transmission method and equipment. Background technique [0002] In the prior art, spectrum can be divided into licensed spectrum and unlicensed spectrum. Among them, the licensed spectrum is a well-divided dedicated spectrum, and its interference is basically predictable. There is no specific application system planned on the unlicensed spectrum, which can be shared by multiple systems, such as LTE (Long Term Evolution, long-term evolution), WiFi (wireless network) etc. Therefore, its interference is unpredictable, and there is great uncertainty in the transmission performance and service quality of its data transmission. When the interference of the unlicensed spectrum is small, the transmission performance and service quality can be accepted. When the interference of the unlicensed spectrum is large When it is large, it will reduce the pe...
